When image information is received, a main controller investigates the blank memory capacity of a floppy disk, after which the main controller executes processing for storing the received image information in an image-information semiconductor memory while confirming that sufficient blank memory remains in the image-information memory. If, during execution of the processing for storing the image information, the blank memory area of the image-information memory runs out so that no further image information can be stored there, or the quantity of image information to be stored in the image-information memory becomes greater than the blank memory capacity of the floppy disk, an error warning is issued, the processing for storing the image information is suspended and processing for interrupting communication is executed.
